I don't know if it has been said before, but rather than the number of fruits, it would be way more accurate to note the number of color changes that occur and in which order they occur. Example totally made of as I have no house nor money :


desert yellow => dark blue +2, dark green +1, light red +1, dark blue +1, light red +1 => othard blue

(this is totally made up and most probably wrong. It's just to put an example for what I'm talking about)
